| Sep-30-21 | | Brenin: White is a pawn down, but 32 e6 wins the exchange: 32 ... Qxe6 (32 ... Qxd4 33 exf7+ Kxf7 34 Qxd8 loses the N) 33 Qxd8+ Nxd8 34 Bxd5 Kf7 35 Bxe6+ Nxe6 36 Re7+ Kf6 37 Rxa7, and White has R vs N, a straightforward endgame win. |
|
| Sep-30-21 | | NBZ: This is a neat puzzle. I am fully in awe that White appears to have foreseen this as far back as move 28, since otherwise he would surely have avoided 28. f4 and played something else. Black must have thought he was winning material with 28... cxb3, since if (after 29. Rxc6 Qxc6 30. axb3 Qc1+) White tries 31. Kf2, then 31... Rc8 is very dangerous. It's hard to blame Black for missing White's brilliant idea of 31. Kh2!! and 32. e6! |

| Sep-30-21 | | raymondhow: Pretty easy, felt more like a Wednesday puzzle. |
|
| Sep-30-21 | | Counterpoint: 32. Bxd5 also wins. |
|
| Sep-30-21 | | Granny O Doul: @counterpoint: On 32. Bxd5 Rxd5 33. Rxd5 Qe2+ White's king does the perp walk. |
|

 | | al wazir: My move was 32. Bxd5.
If 32...Qxd4, then 33. Qxd8#. If 32...Qf2+, then 33. Kh3 (not 34. Kh1 Qf3+ 35. K any Qxd5) Qf1+ 34. Bg2. But it doesn't win, because black has 32...Rxd5 33. Rxd5 Qf2+ 34. Kh3 1/2:1/2. |

| Sep-30-21 | | agb2002: White has a bishop for a knight and a pawn.
Black threatens Qxd4.
The knight protects the rook and the black king is on the diagonal a2-g8. Therefore, 32.e6: A) 32... Qxe6 33.Qxd8+ Nxd8 34.Bxd5 wins the exchange. B) 32... Qxd4 33.exf7+ Kxf7 34.Qxd8 Ke6 (due to Qxd5) 35.Qe8+, followed by Qxb5, wins decisive material. C) 32... Rc8 33.exf7+ is winning. For example, 33... Kf8 34.Qa3+ Kxf7 35.Rxd5. |

 | | ajk68: Does somebody want to explain the winning endgame technique from the final position? I'm thinking all the a- & b-pawns on both sides will fall. It's then R+3pawns vs N+3pawns. The knight and king may be able to keep the rook and king from encroaching into the corner. There's probably a few stalemates hidden in there too. Not to mention white has a backward g-pawn. |

 | | Teyss: <al wazir> Same here (dogs think alike apparently). Thought there was a theme similar to yesterday's about the White LSB, then realised it leads to perpetual at best. So applied the old patzer method of visualising every piece move and e6 came last (I tend to forget about Ps) but is obvious once played.
OTB it's impossible because of time and positions & variations being more complex than here.<ajk68: I'm thinking all the a- & b-pawns on both sides will fall.> That's what I thought too after 37.Rxa7 Nd4 38.b4 Nc2 but if White first plays 37.b4 blocking the BN White can keep his b P and it's an easy win from there. The WR can prevent the BK from passing Qside and use push the P.
Even without the b P it wins but it's a bit longer: the WR will keep the BK on the back ranks and threaten the backward Ps and the WK will march on. Actually the f5 P is about to fall since Black cannot at the same time protect it and take the b P. |

| Sep-30-21 | | TheBish: White to play (32.?) "Medium"
White wins material after 32. e6!, as the knight cannot move, being the only defender for the black rook. So that leaves... (a) 32...Qxd4 33. exf7+ Kxf7 34. Qxd8 followed by 35. Q(B)xd5(+) and White has an extra bishop. (b) 32...Qxe6 33. Qxd8+! Nxd8 34. Bxd5 and White will be up an exchange after the smoke clears. Of course, White needs to see 33. Qxd8+! before giving away the e-pawn the move before. The exclam after the queen (sham) sac is to reflect the dramatic transformation on the board; in one full move (33. Qxd8+ Nxd8) both (1) a defender of d5 is removed, and (2) the black king and queen are set up for a skewer (carried out the next move) by the sudden evacuation of the knight from f7. A lot of words to describe a nice visual, but words are not adequate. Similar to reading a concert review, instead of attending the concert! |

 | | Dionysius1: <TheBish> You're right - such a one-move transformation. This is why I like chess so much: the power to shock me and make me smile. |
|
| Sep-30-21 | | MatrixManNe0: So, correct me if I'm wrong, but I also saw the line 32. e6 Qxd4, but then instead of winning the knight, I went for 33. Qxd8+, with the idea that 33.. Nxd8 (forced) 34. e7 Kf7 transposes to the line everyone else is posting, but it also allows black to slip up with 33.. Qf6 34. Bxd5+ and mate is coming. Better line? Or does it have a problem? |
|
| Sep-30-21 | | MatrixManNe0: Ah, black has 34.. Ne6 in that line. Never mind! |
